The Radial Artery: An Applicable Approach to Complex Coronary Angioplasty.

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Surgery

Background:

• The transradial approach (TRA) is an alternative to the transfemoral approach for percutaneous coronary interventions.
• Assessing the clinical utility and safety of TRA in a real-world setting is crucial for widespread adoption.

Purpose of the Study:

• To evaluate the clinical value and safety of the transradial approach (TRA) in performing coronary angioplasty.
• To determine the success rates and complication profile of TRA in a cohort of patients undergoing coronary interventions.

Main Methods:

• Prospective study of 250 patients undergoing coronary angioplasty via TRA over 18 months.
• Data collection included procedural success, complication rates (major and local vascular), and patient outcomes.
• Analysis of patient demographics, lesion complexity, and additional procedures performed (stenting, rotational ablation).

Main Results:

• High angiographic success rate of 97% with no reported deaths.
• Low rates of major procedural complications (0.8% Q-wave MI, 2.0% non-Q-wave MI, 0.8% urgent CABG, 0.8% CVA).
• Minimal local vascular complications (0.4% compartment syndrome, 1.6% pseudo-aneurysm), with 93% maintaining palpable radial pulse at discharge.

Conclusions:

• The transradial approach (TRA) is a safe and effective method for performing complex coronary angioplasty.
• TRA is associated with a low incidence of vascular complications, making it a valuable alternative to the transfemoral approach.
• No patient experienced hand ischemia, highlighting the safety profile of TRA for limb perfusion.
